To all `whom it may concern..- y

Be it known that we, ETHAN R. CHENEY, of Boston, in the county ofSuffolk and, State of Massachusetts, and JOHN J. EMERY, of Owls Head, inthe county of Knox and State of Maine, have invented certainImprovements in Chain Stoppers or Holders, of which the following is aspecification.

This invention is an improvement upon that l described in the patent ofJ. J. Emery, issued Septe1nber21, 1869, and re-issued to himself it isforced by the recoil of the springs, and to the arrangement ofsupporting stay-rods for the guides and standards, all as more fully setforth below.

Figure l represents a perspective view of a l portion of a vessel `andthey improved chain stopper or holder as applied to the vessel and thecable. Fig. 2 is a sectional side elevation.,

VLetter A designates the-movable chaini i holding part, which isprovided with the pawl C,to grip the cable. This part A is supported iupon guide-rods X, supported in turn by the l standards E G.

To the after end ofthe rods or guides X D are secured the rods J, whichextend in the aft direction, andare firmly secured to the Thesestay-rods Jare of great consequence in connection with the necessaryframe-like construction of the ap paratus, and, acting in opposition tothe strain exerted through the cable, afford great se-V The part A isresisted in the forward direction by curity and .strength to theapparatus.

means of springs F, interposed between it and the standards E.I Whenstrain is applied to the Chain or cable B, as is the caseto a greater orlesser extent when the vessel is riding at anchor, the part A is drawnforward toward the standards E. Whenever the strain is relaXed, thesprings recoil, and if the relaxation is sudden the part A will bethrown backward by the recoil somewhat violently.

To overcome the shock occasioned by the part A being thrown in thismanner against the standard G, We have provided between it and thestandard G the elastic cushion H, which relieves the. shock and preventsdanger of breakage.
